About

I am currently a PhD candidate in computer vision at the University of Paris-Saclay. I work on Sign Language translation with Annelies Braffort, Michèle Gouiffès, Gül Varol and Andrew Zisserman. I am interested in applications of machine learning with social impact and would like to work in the high-tech manufacturing industry. I also love teaching mathematics/statistics-related classes.

Prior to my PhD, I graduated from the MVA program at the ENS Paris-Saclay. I also studied mathematics and econometrics, and spent 2 years working as a Data Scientist in a software start-up.
